Project description:The purpose of this Technical Note is to introduce a surgical technique using a fluid pressure pump, mid-lateral portal, and radiofrequency ablation for visualization, assessment, and subsequent, accurate/adequate removal of patellofemoral articular lesions for the treatment of patellofemoral compartment pathology. With the patient in the supine position, and an inflated thigh tourniquet, standard lateral and medial portals are made. The medial-femoral compartment, notch, lateral-femoral compartment, and patellofemoral compartments are assessed. If pathology is seen within the patellofemoral compartment, a mid-lateral portal is made if chondral pathology cannot be addressed thoroughly. Addressing chondral pathology to achieve chondral stability is then performed using a combination of the radiofrequency ablator and chondrotome. This technique provides greater visibility and access to accurately and thoroughly smooth chondral pathology.

Project description:Knee osteoarthritis is the most common orthopaedic disorder, and surgical treatments are always inevitable. Among the various surgical options, arthroscopic treatment is not favorable because strong evidence supporting its application is scarce. However, we consider that the unsatisfactory clinical results of arthroscopic surgery occur because the pain-relieving mechanism of joint replacement is not realized in the too simple and not well-designed arthroscopic procedures. Thus, we use a set of arthroscopic procedures to realize the pain-relieving mechanism of joint replacement, which we call "arthroscopic arthroplasty." The most important parts of this technique are denervation of the subchondral bone and comprehensive synovectomy. Our clinical results indicate that we can obtain even better functional improvement with this technique than that with joint replacement. We consider that the introduction of this technique will arouse interest in the development of arthroscopic surgical procedures for knee osteoarthritis.

Project description:UNLABELLED: Isolated patellofemoral osteoarthritis in the healthy middle-aged population is a challenging problem. Fifty-one knees in 50 patients with isolated patellofemoral osteoarthritis were treated by partial lateral facetectomy, lateral release, and medialization of the tibial tubercle. The minimum followup was 7 months (mean, 20.2 months; range, 7-32 months). Preoperative radiographs showed Ahlbäck Grades III and IV lateral patellofemoral joint space narrowing. The mean age of the patients was 60.1 years (range, 46-81 years). The subjective outcome was based on the WOMAC and the McCarroll score. Posteroanterior flexion weightbearing views, lateral views, and 45 degrees axial views were taken. According to the WOMAC score, the scores improved considerably by 2.34 points with respect to pain and by 1.63 points with respect to function. The Insall-Salvati index decreased considerably but still remained in the physiologic range. The majority of these patients experienced improvement in their patellofemoral symptoms. However, the clinical outcome was not better in comparison to other surgical procedures. After the short followup, we would not recommend combined lateral facetectomy, lateral release, and medialization of the tibial tubercle until longer results are available. LEVEL OF EVIDENCE: Level IV Therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Project description:BackgroundPatellofemoral crepitus is an unfavorable complication following total knee arthroplasty (TKA) with a posterior-stabilized (PS) implant. The purpose of this study was to study patellar crepitus recurrence and reoperation rates following arthroscopic debridement in patients with a PS-TKA.MethodsOur institution database was used to identify patients with a PS-TKA who underwent arthroscopic debridement for patellofemoral crepitus at our institution. Patients must have had a resurfaced patella and minimum 2 years clinical follow-up from the arthroscopic debridement to be included in the study. Recurrence of patellar crepitus, subsequent operations, and any adverse events were documented.ResultsWe identified 35 patients who met inclusion criteria with an average follow-up of 8.0 years (range 2.1 to 18.4 years) from their arthroscopic debridement. Nineteen patients (54.3%) had history of a nonarthroplasty knee surgery prior to their TKA. The mean time interval between TKA and arthroscopic debridement for patellar crepitus was 1.6 years (range 0.2 to 5.0 years). Overall, 16 patients (45.7%) developed recurrent crepitus (8 asymptomatic and 8 symptomatic). Six of the symptomatic patients (17.1% of the entire cohort) underwent a repeat surgery for recurrent patellofemoral crepitus. Of theses 6 patients, 3 developed recurrent crepitus but only 1 patient had a third surgical procedure. No postoperative complications were noted following any surgical procedure. The mean knee range of motion following arthroscopic debridement did not change (126.9° preoperatively vs 127.0° postoperatively).ConclusionsPatients experienced high rates of recurrent patellofemoral crepitus following arthroscopic debridement. One-sixth of the patient cohort required a second surgical intervention for recurrent crepitus.

Project description:BackgroundIsolated patellofemoral (PF) osteoarthritis (OA) affects 9% of persons older than 40 years. Nonoperative treatment should be exhausted fully before surgical treatment.Questions/purposesThe purpose of this article is to review the literature after 2008 with the aim of answering the following question: Which of the following surgical procedures has the highest survival rate and the lowest revision rate in advanced isolated PF OA: patellofemoral arthroplasty (PFA), total knee arthroplasty (TKA) or lateral facetectomy.MethodsThe search engine was MedLine. The keywords used were: PF OA and PFA. Three hundred and fifty-three articles were found between 2008 and 25 July 2013. Of those, only 23 were selected and reviewed because they were strictly focused on the topic and the question of this article.ResultsThe types of studies reported so far have a low level of evidence (levels III and IV). Most of them are prospective case series (level IV). Some are systematic reviews of level III studies. Reported survival rate of lateral facetectomy is 85% at 5 years, 67% at 10 years and 47% at 20 years. Reported failure rate of lateral facetectomy is 26% at 10 years and 16% at 12 years. The reported average time of reoperation is 8 years and 37% of such procedures fail. Survival rate of PFA has been reported to be 87.5% on average (range, 60-100%). The revision rate of PFA is 20%. Recent improvements in PFA design have resulted in improvements in short-and medium-term results, similar to those of TKA.ConclusionsThere is still no gold standard for the surgical treatment of isolated PF OA. However, PFA or TKA appear to be the most recommendable treatment in cases that do not respond to conservative treatment.

Project description:PurposeTo evaluate whether the bony impingement lesion in elbow osteoarthritis can be removed accurately, as planned during arthroscopy, by using the computer-aided navigation system and performing mock surgery using 3-dimensional (3D)-printed bone models for clinical applications.MethodsWe performed mock surgery using 3D-printed plaster bone models of the humerus of 15 actual patients with elbow osteoarthritis. Two types of experiments were conducted to evaluate the surgical accuracy. Three surgeons performed the mock surgery, each with 15 bone models (total, 45 trials). Surgical accuracy was based on the mean of 45 trials. The differences in surgical accuracy among the 3 surgeons were also evaluated (mean 15 trials). The same surgeon performed 30 trials, and the difference in surgical accuracy between the first and the second halves was also evaluated (mean 15 trials).ResultsThe spatial error in the entire elbow joint was 1.13 mm. In terms of resection volume, a mean of 8% more volume was resected than was planned, and 85% of the planned area was resected. In our experiments, the surgical accuracy was significantly lower in the anterior than in the posterior joint. Intrarater reliability was intraclass correlation (ICC)2,1 0.81 and inter-rater reliability was ICC1,1 0.87.ConclusionsSurgery using computer-aided navigation systems for arthroscopic debridement of the elbow provided accuracy comparable to that in other joints.Clinical relevanceArthroscopic debridement of elbow osteoarthritis requires advanced surgical skills because accurate identification of the bony impingement legion is difficult during surgery. Surgery using computer-aided navigation systems for arthroscopic debridement of the elbow will provide real-time tracking of both the surgical instruments and bony impingement lesions as well as solve the technical difficulties of arthroscopic surgery of the elbow joint.

Project description:BackgroundIsolated patellofemoral osteoarthritis (PF-OA) is a common subtype of knee osteoarthritis, leading to a huge economic burden on health care systems. Although previous studies have shown that patellofemoral arthroplasty (PFA) and total knee arthroplasty (TKA) have good clinical effects, it remains largely unclear which treatment is more effective for patients with isolated PF-OA. We aimed to compare postoperative function, complications, revision rates, level of physical activity, and satisfaction rate between the two surgical techniques.MethodsOur study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Search of literature was conducted in MEDLINE, EMBASE, Cochrane Library, and Web of Science until November 2020. The included studies were those that provided direct comparison of postoperative outcomes between PFA and TKA. Data were extracted from eligible studies and combined to calculate the pooled odds ratio (OR) and 95% confidence interval (CI). Sensitivity analysis and subgroup analysis were conducted to evaluate heterogeneity between the two groups.ResultsA total of 7 eligible studies (3 recent randomized controlled trials and 4 nonrandomized controlled trials) were included in this meta-analysis. The pooled results showed that both the PFA group and the TKA group had improved postoperative indicators, suggesting that the two operation modes could improve the knee function and quality of life of patients. Throughout the first 2 years postoperatively, higher activity level, and better functional recovery were observed for PFA compared with TKA in this study; moreover, the differences between the two operation modes were statistically significant (p < 0.05). We found no significant difference in complications, revision rates, and satisfaction rate between the two procedures.ConclusionAlthough there was no observed difference in the complications, revision rates, and satisfaction rate between PFA and TKA, PFA was superior to TKA in terms of knee function and physical activity in the first 2 years postoperatively. Therefore, PFA is a safe, effective, and less invasive treatment for patients with isolated PF-OA. Our findings are consistent with the systematic review of current evidence that PFA may be more suitable for younger patients with high activity needs. Patient selection is, therefore, thought to be of paramount importance. Individualized surgical plan should be designed according to the patient's age, BMI, KOA site, and activity level and combined with the doctor's personal experience.

Project description:Tenosynovitis of the flexor hallucis longus tendon is a condition typically found in ballet dancers and sometimes in soccer players and is related to chronic overuse. It mostly involves the portion of the tendon behind the ankle joint. However, the portion of the tendon under the sustentaculum tali can also be involved. Open synovectomy requires extensive dissection. We report the technique of arthroscopic synovectomy of the deep portion of the flexor hallucis longus.

Project description:Arthroscopic debridement for elbow osteoarthritis has been widely used as a minimally invasive treatment; however, in some cases, it can be a technically demanding procedure, such as in patients with severe osteoarthritis with large spur formation and severe synovitis. The anterocentral transbrachialis portal is a recently developed portal for elbow arthroscopy, which allows easy and convenient access to the anterior compartment for sufficient debridement. This report describes in detail the anterocentral transbrachialis portal and its usefulness for debridement of the elbow joint in osteoarthritis.

Project description:Synovitis of the interphalangeal joint of the great toe can occur in patients with rheumatoid arthritis, seronegative arthritides, or gouty arthritis or after a penetrating injury to the joint. Complete synovectomy of the joint usually requires a lengthy incision and extensive soft-tissue dissection. The purpose of this Technical Note is to describe the surgical details of arthroscopic synovectomy of the hallucal interphalangeal joint, which can reduce the surgical trauma.
